My first Handi was a .243 in standard contour, and although it wasn't terrible, it wasn't very consistent in it's grouping. That could have been my newbie approach to Handi's or the fact that I only tried about four different factory loads at the time, and since I didn't reload, it got a little expensive so I moved on to other calibers and was quite pleased, with the results.
I had then read a lot of the negative posts on the .243 and a lot of possitive ones so I left that option open for when the right deal came along.
It did last year, when I found one in the classifieds, and it was a .243 in a 24" Ultra bull barrel.
I did a little research in the archives on the barrel and some detective work, finding exactly who had owned the barrel previously, and found that it was in fact from a complete new rifle, and had never been parted, so that was in my favor that it could fit my frames.
I also noted that the previous owner had done a lot of ground hog hunting, and he was shooting groups at 100 yards and beyond, and consistently getting groups you could cover with a dime.
I bought that barrel, and it has been my best shooter to date and I have no thoughts of ever selling it!
There are good one's out there!
